Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for operating electric equipment such as a blind opening/closing motor provided in a sash or a security device from a remote location.

Conventional technology Electric equipment such as motors for opening/closing blinds and security equipment installed inside the sash are installed at a high place or close to the floor, and the operating section is installed in the middle of the upper and lower positions to make it easier for people to operate. 2. Description of the Related Art An operating device is known in which a controller of an electric device and an operating section are connected by cable wiring so that the operating section can be operated from a remote location from the controller of an electric device.

Problems to be Solved by the Invention With such an operating device, it is necessary to route cables connecting the controller and the operating section inside the sash, which is a very troublesome task. In particular, in the case of so-called retrofitting, in which electrical equipment is attached after the sash has been assembled, cable wiring work becomes particularly troublesome.

Furthermore, the cable sheathing part of the cable wiring may be cut by the sharp part of the sash, so there is a risk of electrical leakage.

Additionally, signals may be input to the cable wiring due to disturbances, resulting in malfunctions.

Means and action for solving the problem: A controller for an electric device installed in a sash frame constituting a sash, an operating section installed in a hollow vertical member of the sash frame, and an operation section on this operating section and the controller side. A light emitting element and a light receiving element are provided so that the light receiving element receives light when the unit is operated from a non-operating position to an operating position, and the controller rotates the electric equipment in the forward, reverse, or stop direction depending on the number of times the light receiving element receives light. In this way, the electric equipment can be operated from a remote location, and there is no need to use cable wiring.

Example: The frame body 1 constituting the sash has an upper horizontal member 2 and a lower horizontal member 3.
The left and right vertical members 4, 4 form a rectangular frame shape, and a blind 5 is disposed inside the frame, and the blind 5 is made up of a number of slats 6 connected by cables 7 so as to be able to rise and fall freely. It is wound around a pulley 9 fixed to a rotating shaft 8 horizontally suspended in the upper horizontal member 2, and this rotating shaft 8 is connected to a motor 10, which is an electric device, and the motor 10 is driven and controlled by a controller 11. , a mounting body 12 is attached to the top of the vertical member 4.
are provided, and an operating section 13 is provided at an intermediate position between the upper and lower sides.

The mounting body 12 has a light emitting element 14 and a light receiving element 1.
5 are provided adjacent to each other facing downward, and the operating portion 13 is provided with an operating rod 18 provided with a reflecting plate 17 in a cylindrical housing 16 so as to be freely retractable. The operating rod 18 is inserted and fixed so as to protrude inward from a hole 19 formed in the housing 16, and the operating rod 18 is biased by a spring 20 so that the reflecting plate 17 is housed in the housing 16.

The light emitting element 14 and the light receiving element 15 are connected to the controller 11 to which a control signal is input, and power is supplied to the light emitting element 14 to emit light.
The optical path between the reflector 17 and the reflector 17 is free of any obstacles.

However, when the operating rod 18 is not pressed, the reflection plate 17 is housed in the housing 16, so the light emitted from the light emitting element 14 reaches the lower part of the vertical frame 4 and is not received by the light receiving element 15. No control signal is input to the controller 11, and the motor 10 is stopped.

The reflector 17 that pushes the operating rod 18 is the housing 1
6, the light from the light emitting element 14 is reflected and received by the light receiving element 15, so a control signal is input to the controller 11, and the motor 10 rotates in the normal direction for a period of time determined by the controller 11, so that the rotating shaft 8 rotates. Then, the cable 7 is wound up and the blind 5 is opened.

When the operating rod 18 is pressed twice intermittently, the light receiving element 15
Since the blind 5 intermittently receives the light twice, a control signal is intermittently inputted to the controller 11 twice, which causes the motor 10 to rotate in the reverse direction, so that the blind 5 lowers under its own weight and closes.

In addition, when stopping the blind 5 midway, as described above, a stop signal is output to the controller 11 by pressing the operating rod 18 three times in succession while the motor 10 is rotating forward or reverse. Just do it.

As shown in FIG. 6, the operating section 13 has an operating rod 18 rotatably provided with a reflector 17 in a housing 16, and the operating rod 18 is formed by a spring 21, a cam 22, and a cam recess 23. The reflecting plate 17 may be held in a position upward from the opening 16a of the housing 16 and in a vertical position.

In addition, as shown in Figures 7 and 8, the operating lever 1
First and second filters 2 that pass light of different wavelengths to 8.
4 ₁ , 24 ₂ first and second reflecting plates 25 ₁ , 2
5 ₂ is attached to the mounting rod 12, and the first and second light receiving elements 15 1 are provided with third and fourth filters 24 ₃ and _{24 4 having} the same properties as the first and second filters 24 1 and _{24 2} . , 15 ₂ may be provided.

In this way, when the operating rod 18 is rotated so that the first reflecting plate ₂₅₁ faces upward, the first and third
Since the filters 24 ₁ and 24 ₃ transmit the same color,
The light from the light emitting element 14 is received only by the first light receiving element 15 ₁ , and when the operating rod 18 is rotated so that the second reflecting plate 25 ₂ faces upward, the light is passed through the second and fourth filters 24 ₂ ,
24 ₄ transmits the same color, only the second light receiving element 15 ₂ receives the light from the light emitting element 14.

Therefore, when the first light receiving element 15 ₁ receives light, a motor forward rotation signal can be input to the controller 11, and when the second light receiving element 15 ₂ receives light, a motor reverse rotation signal can be input to the controller 11, and by rotating the operating rod 18, the motor 10 can be reliably operated. Normal rotation/
It can be reversed.

9 to 11 show other embodiments, in which a light receiving element 15 is provided on the mounting rod 12, and an operating section 13 is provided.
A battery 30 is provided in the housing 16, the (+) side of the battery 30 is connected to the light emitting element 14 via a resistor 31, and the (-)
The side is connected to the light emitting element 14 via a switch 32, and the switch 32 is composed of a rotating contact piece 34 pushed by a spring 33 and a fixed contact piece 35, and the rotating contact piece 34 is pressed against the spring 33. When pressed, it connects to the fixed contact piece 35.

In this way, when the rotary contact piece 34 is pressed, the light emitting element 14 emits light and the light receiving element 15 receives light, so that the motor 10 can be rotated in the forward or reverse direction depending on the number of times the rotary contact piece 34 is pressed as described above. The blind 5 can be driven to open and close, and can also be stopped midway.

Further, since the battery 30 and the light emitting element 15 are provided in the operation unit 13, the light emitting element 15 can be used even when the power source of the controller 11 cannot emit light.

As shown in FIG. 12, the light emitting element 14 is made to emit light by an oscillator 37 provided on the circuit board 36, and the first operation button 38 is connected to the first contact 39.
If the second operation button 40 is configured so that when it comes into contact with the second contact point 41, the dot reduction period of the light emitting element 14 becomes shorter, and when the second operation button 40 touches the second contact point 41, the dot reduction period of the light emitting element 14 becomes longer. By pressing the buttons 38 and 40, the light-receiving element 15 receives light with different dot and dimming cycles, which allows two control signals to be input to the controller 11, so the motor 10 can be accurately rotated in the forward and reverse directions. . In this case, a button battery may be provided on the circuit board 36.

In the above embodiments, the motor for opening and closing blinds has been described, but the present invention is not limited to this and can also be used to operate security equipment.

Note that it is preferable that the light emitted from the light emitting element 14 be modulated light, and doing so is convenient when sending signals having multiple meanings.

Effects of the invention: By operating the operating unit 13 installed apart from the controller 11 of the electric device to the operating position, the light receiving element 15 receives light, and the controller 11 can thereby drive the electric device. In addition to being easier to operate, since the light emitting element 14 and the light receiving element 15 are used, there is no need for cable wiring, and even if it is retrofitted, it can be easily installed, and there is no fear of malfunction due to electric leakage or noise.

In addition, since it receives light and outputs a control signal to the controller 11 only when the operation unit 13 is operated to the operating position, compared to a device that receives light all the time and outputs a signal to the controller 11 when the light is blocked, it may not receive light for some reason. Since no control signal is output even if the light emitting element or light receiving element is lost, there is no malfunction, and failure of the light emitting element or light receiving element can be immediately detected.

In addition, a light emitting element 14 is provided in the hollow part of the vertical member 4 of the frame body 1.
Since the light receiving element 15 is arranged, the sash is not affected by light flying around the sash, and there is no fear of malfunction.

Furthermore, by operating the operating unit 13 multiple times between the non-operating position and the operating position, the number of times the light-receiving element 15 receives light can be changed, thereby allowing the controller 11 to control the operations of the electric equipment, such as forward rotation, reverse rotation, and stopping. , it is only necessary to change the number of operations of the operating section 13, and a complicated signal output circuit is not required, resulting in a simple structure.
